The sign by the F-1 engine. It reads
The Power of Apollo
The most powerful liquid-fueled rocket engine ever produced, the F-1 engine was
a critical component in sending Astronauts [sic] to the moon during the Apollo
program. Developed under the direction of Werner [sic] Von [sic] Braun, the
Saturn V rocket was the largest operational launch vehicle ever produced.
Standing 36 stories high and weighing over 6 million pounds, a cluster of five
F-1 engines, generating more than 7.5 million pounds of thrust propelled the
rocket to a speed of 6,000 mph and an altitude of 38 miles in just under three
minutes. It was said at the time that, except for a nuclear explosion, the
launching of the Saturn V rocket was the loudest man made noise ever produced.
Just one F-1 engine provided as much thrust as all three Space Shuttle Main
Engines combined!
Fuel: Liquid Oxygen (LOX) and RP-1 (Kerosene)
